One of my students suggested reducing Output Colors option from the default “Millions” setting. That seems to deal with the problem, thankfully.

I haven't observed the problem you describe on my Mac, which is a three- or four-year-old MacBook Pro (that is, the Rcmdr dialogs display reasonably crisply for me), and I haven't done anything special to configure XQuartz. Here are the specs for my Mac:

 Model Name:	MacBook Pro
  Model Identifier:	MacBookPro13,2
  Processor Name:	Dual-Core Intel Core i7
  Processor Speed:	3.3 GHz
  Number of Processors:	1
  Total Number of Cores:	2
  L2 Cache (per Core):	256 KB
  L3 Cache:	4 MB
  Hyper-Threading Technology:	Enabled
  Memory:	8 GB
It might help to have some more information. I assume that you're using the most recent versions of R, the Rcmdr package, and other packages, and a recent version of macOS. What Mac do you have, and did you reboot it after installing XQuartz? If you updated R, did you reinstall XQuartz?
